ToArray Method

Overview

The ToArray method converts observable data table into array of observable data rows.

Declarations

/// <summary>
/// Returns a shallow copy of the table's observable rows as array
/// </summary>
/// <param name="observableDataTable">Observable data table</param>
/// Array of observable rows
public static IObservableDataRow[] ToArray(this IObservableDataTable table)

Namespace and Assembly

Namespace: PocoDataSet.ObservableExtensions
Assembly: PocoDataSet.ObservableExtensions.dll

Usage Example (Interface-based)

// 1. Create observable data set
IObservableDataSet observableDataSet = new ObservableDataSet();

// 2. Create Department observable table with rows in different states
IObservableDataTable departmentObservableDataTable = observableDataSet.AddNewTable("Department");
departmentObservableDataTable.AddColumn("Id", DataTypeNames.INT32);
departmentObservableDataTable.AddColumn("Name", DataTypeNames.STRING);

// Row in Added state
IObservableDataRow departmentObservableDataRow1 = departmentObservableDataTable.AddNewRow();
departmentObservableDataRow1["Id"] = 1;
departmentObservableDataRow1["Name"] = "Reception";

// Row in Deleted state
IObservableDataRow departmentObservableDataRow2 = departmentObservableDataTable.AddNewRow();
departmentObservableDataRow2["Id"] = 2;
departmentObservableDataRow2["Name"] = "Emergency";
departmentObservableDataRow2.AcceptChanges();
departmentObservableDataRow2.Delete();

// Row in Modified state
IObservableDataRow departmentObservableDataRow3 = departmentObservableDataTable.AddNewRow();
departmentObservableDataRow3["Id"] = 3;
departmentObservableDataRow3["Name"] = "Emergency";
departmentObservableDataRow3.AcceptChanges();
departmentObservableDataRow3["Name"] = "Finance";

// 3. Call ToArray method and verify that array contains all three rows
IObservableDataRow[] observableDataRows = departmentObservableDataTable.ToArray();
